In my project,I connect the ADV7612 & ADV7511 with a FPGA. I connect the audio signals of ADV7612 directly to those of ADV7511.The ADV7612 & ADV7511 are from diffrent PCB borad. So their colcks can not be exactly the same. I am afraid the slight differences in those clocks
can cause the FIFO in ADV7511 overflow or underflow.How could I solve this problem?
